Opis:: Contemporary aeronautical constructions require applying systems of drive transmission based on gear units. Trends in development of aeronautical gears assume diminishing weight of the gear retaining its basic features which are; the possibility of transmitting high load and reliability. The article presents an analysis of criterion for choosing constructional solutions for aeronautical multi-power path gear units. A few criteria were chosen for the analysis: constructional solutions of aircrafts (planes, helicopters), constructional solutions of engine- moment receiver system and a kind of applied drive. Because the field of issues connected with aeronautical drive transmission systems is very wide, the material and technological factors were not taken into account. They are a subject of separate analysis. The main aim of the presented analysis is determining the criterion for choosing constructional solutions of drives based on existing solutions which allow for implementing new solutions for newly developed aeronautical constructions on the prototype stage. Modernising existing constructional solutions is difficult to put into practice because of procedures followed in the aeronautic industry. That is why the carried out analysis aims at preparing solutions for research on the stage of making a virtual and demonstrative prototype. The final effect of such analysis and research can be developing a solution for gear unit parts assuring the possibility of transmitting a given moment while diminishing, for example, weight in comparison to gears which are produced nowadays. This factor is extremely important for parts of aeronautical constructions.

Opis:: The paper presents preliminary stand tests of a demonstrator of planetary gearing. The gearing used in the research has been made of ABS polymer with good strength parameters. Parts of the gearing have been created by means of FDM (Fused Deposition Modeling). The input data come from 3D CAD solid model which geometry is determined by a file of any system equipped with the ability to save in STL format. This model is described by a grid of triangles and divided into levels (layers). Their thickness determines the accuracy of representation of a detail curvature. The thickness of the layers is also limited by the accuracy of the process and the equipment. The research was conducted on a test stand designed in an open system powered by a three-phase electric motor. The control is provided by a single-phase inverter with three outputs, which ensures full speed control. The load of the stand is realized by an electromagnetic powder brake. The possibility to control working time lets you precisely define the time intervals of various stages of the research. Using timer makes it possible to observe the current consumption of the gearing and helps to establish the research process. The research at this stand allows for obtaining stable working parameters and thus for obtaining accurate, not distorted results of the demonstrator’s operation. The purpose of the research is verification of gear endurance calculations and verification of the design in conditions similar to real ones.

Opis:: One of the phases of existence of machinery according to [5], is among others, constructing. The aim of constructional diagnostics used in this case is to identify sources of potential risks. In a dual-path gear transmission power is transferred by two parallel paths. Due to backlash and precision of making the whole gearing, the power is not transferred evenly along both paths. It creates potential risk which makes it necessary to create such gearing with higher module. This in turn causes an increase in dimensions and weight of the gearing. The paper presents a technical solution that allows to delete backlash on teeth on all stages of the gear transmission and thus increase the uniformity of power distribution into two paths. The solution consists in applying an intermediary split shaft whose parts can be exactly positioned angularly in relation to each other in the process of assembling the gear transmission.
Jedną z faz istnienia maszyny wg [5] jest m. in. konstruowanie. Celem stosowanej w tym przypadku diagnostyki konstrukcyjnej jest identyfikacja źródeł potencjalnych zagrożeń. W przekładni dwudrożnej moc przekazywana jest dwiema równoległymi drogami. Z uwagi na luzy i dokładność wykonania całej przekładni moc nie jest przekazywana równomiernie. Stanowi to potencjalne zagrożenie, które pociąga za sobą konieczność wykonywania takich przekładni o zwiększonym module, co z kolei jest przyczyną zwiększenia gabarytów i masy przekładni. W artykule przedstawiono rozwiązanie techniczne pozwalające na skasowanie luzu między zębami na wszystkich stopniach przekładni a tym samym zwiększające równomierność rozdziału mocy na dwie drogi. Rozwiązanie polega na zastosowaniu dzielonego wału pośredniego, którego części mogą być dokładnie pozycjonowane kątowo względem siebie w procesie montażu przekładni.

Opis:: An instantaneous contact track is one of theparameters determining correct work of wheels in gears. It is the surface on the side of the tooth on which a contact is made with the cooperating surface of the other wheel in a given moment. The correctness of cooperation of wheels and kinematic accuracy of the gear depends on the shape and the size of an instantaneous contact track and its changes during rotation of wheels. Both the area of contact track and its position also depend on the greatness of load being in operation. Therefore it is important to carry out calculations for conditions of work which are the closest to real working conditions of aeronautical bevels gear. At the designing stage an instantaneous contact track can be determined by means of finite elements method (FEM). The article presents a methodology of defi ning contact track for loaded bevel gear by means of numerical finite elements method. The paper also presents Information about creating virtual models ofwheels, generating network of finite elements, defining edge conditions as well as carrying out calculations and processing the received results. Finally, it also presents the received solutions concerning the distribution of reduced stresses andan instantaneous contact track as well as the summary track of wheel teeth cooperation in a loaded bevel gear. However the results received by means of simulation of virtual models cooperation require verifying by other methods, favourably experimental ones. The received numerical solutions made using finite elements method were therefore compared to proper results recorded during examining real models of the same wheels. The examination was carried out on a special stand which had been designed end created for this purpose. The used wheels had been made by means of rapid prototyping method.

Opis:: Gears used for the tests may be made of metal or plastic [1, 2, 5]. The stand has been designed in an open system and it is powered by a three-phase electric motor. The control is provided by a single-phase inverter with three outputs, which provides full speed control. All components have been installed on a table equipped with T-slots in order to determine the optimal position of the drive and the tested gear. The load of the stand is realized by an electromagnetic powder brake. Load torque of the gear depends on the supplied current. During the test, you can change settings such as speed or load torque. Torque meters installed on input and output of the demonstrator let you control the work of the whole gear. Values supplied by the torque meters (torque and speed) are recorded on a computer in real time (according to PC RTC) and archived by specialized software. The software installed on your computer allows you to view results of the measurements. The possibility to control working time lets you precisely define the time intervals of various stages of the research. Using timer makes it possible to observe the current consumption of the transmission and helps to establish the research process. Thanks to data, recording you will know when the gear is damaged. Tests at this stand allow for obtaining stable working parameters, and thus for obtaining not distorted, accurate results of the demonstrator operation. Changing the gear is exceptionally simple because of the use of sliding splined connections of the couplings. Separating couplings between which the gear is situated and unlocking, the terminal allows exchanging it.

Opis:: A constant tendency in the development of gear transmission is aiming for increasing its load capacity and minimalizing its outside dimensions and weight. It is particularly important in automotive vehicles. In every type of transmission, among others in gear-boxes, mainly involute profile wheels are used. The work presents analysis of possibility of applying a typical meshing in driving units of cars. This kind of meshing can be alternative to involute meshing which is most widely used in gear transmission. Among existing solutions of this type, Nowikow meshing is applied most often. A different kind of concavo-convex gearing is BBW type gearing. The gearing is obtained by generation with a tool with reference profile in which tooth profile of a rack is an involute. The analysis of possibility of applying has been carried out with the exemplary concavo-convex BBW type gearing. In BBW type gearing a wheel with a smaller number of teeth has a positive profile curvature, and a cooperating wheel has a negative curvature. Teeth profiles are conjugate ones, transverse contact ratio is higher than l, so this kind of gearing may be used also in gears with straight teeth. What is more linear contact occurring along the whole width of mating teeth, in comparison to point contact in Nowikow meshing, creates possibilities of obtaining higher load capacity of gearing. BBW gearing based on involute-derivative tooth profiles is characterized by smaller sensitivity to the change of axle distance than Nowikow meshing.

Opis:: This paper presents an analysis of the feasibility of using the model similarity method in engineering design. The analysis applies to virtual and physical models of the flexspline body of harmonic gear drive. The task consisted in determining stress distribution in the virtual models of the flexspline by means of the finite element method (FEM) and next its verification during bench tests by the extensometer method. The values of stresses calculated by the FEM method and the extensometer method were compared with each other with the aim ofdefming model similarity. The numerical calculations were made by means of the ADINA application which uses FEM with the use of contact elements. Stress distribution calculations applied to simplified virtual models of the flexspline. By the simplification of models a great number of finite elements used for the discretisation process were limited and because of that the time of calculations was shortened. The simplified model was precise enough to determine the stresses in the flexspline body. The subject of this analysis was the impact of different values of the torque moment T2 on the stresses in the flexspline body of the harmonie drive. The results of numerical calculations were checked against the standing tests of the real drive by applying the extensometer method. During the work of the gear, the values of relative elongation were measured and, based on them, the values of stresses were determined and compared to the results of the numerical calculations by FEM in the analogous cross-sections of the flexspline. The comparability of the results received by both methods proves both that the models used in the numerical calculations were properly designed and that the assumptions as well as the calculation were properly made. The determining of model similarity for the examined harmonie drive will make it possible to carry out analyses of stress calculations by FEM on virtual models without the necessity to verify them by laboratory standing tests each time.

Opis:: The paper contains a strength analysis of gears in a dual-path gearing made of plastic. Computation was carried out using Abaqus program by means of finite elements method (FEM). The results of calculations allow the interpretation of the results of diagnostic tests. Due to the fact that the dual-path gearing had wheels with straight teeth, it was possible to simplify the computation using two-dimensional models. The paper shows activities related to preparation of models, defining boundary conditions, the process of computation and the presentation and interpretation of obtained results. In the carried out FEM analysis, stress distribution was determined on models of pinions and gears, paying particular attention to key points like teeth feet or their flanks. In order to improve readability of these solutions and to ease interpretation, some results were also presented in a form of charts. Conclusions drawn from the analysis will make it possible to introduce conceivable changes in the structure of designed gearing already at the stage of modelling.

Opis:: The article presents methodology of modelling and prototyping process for the demonstrator of aeronautical planetary gear. Contemporary methods of designing gear make use of computer aided designing systems (CAD), computer aided engineering (CAE) and computer aided manufacturing (CAM) including also rapid prototyping (RP). First stage of designing gear is always defining basic parameters of the gear work (among others: transmission ratio, rotational speed, power) determined by the gear destination. After carrying out the gear calculations it is possible to create 3D-CAD models ofwheels and other elements of the gear. 3D-CAD systems are often equipped with a module for analysing geometrical parameters and cooperation of its individual elements e.g. the track of cooperation. A detailed analysis of cooperation of gear wheels' elements allows for early detection of construction mistakes of models and for deleting the mistakes. If 3D-CAD models are made correctly, it is possible to record the geometrical data in an appropriate format of numerical data. The following stage of making the prototype of the gear is preparing numerical data necessary for making the demonstrator by means of rapid prototyping method. The accuracy of making physical prototype depends a lot on the accuracy of 3D-CAD/3D-RP model made by means of processing the numerical data. The demonstrator allows for analysis of constructional solutions of the gear based on physical model and for doing introductory stand tests. The paper presents the process of making the demonstrator of planetary gear applying 3D-CAD modelling and Rapid Prototyping. For making the physical prototype a Fused Deposition Modelling (FDM) method of Rapid Prototyping was applied.

Opis:: The paper presents methodology of increasing the accuracy of models of gears made applying additive methods. As a part of activities related to this subject, it was necessary to develop 3D-CAD research gears, which were the basis for producing physical models made using incremental FDM manufacturing technology. The created models were verified in order to determine the accuracy of resulting geometry. Then modifications were introduced to models so as to increase their accuracy. On this basis, in an iterative process, compensation coefficients were calculated to ensure reduction of defects in geometry with respect to a nominal 3D-CAD model.

Opis:: Air gears must meet high performance criteria for accuracy; therefore, quality control is necessary for their production. CMM Software determines the capabilities and scope of the measuring machines. Measuring machines equipped with specialized software for the measurement of the gears are commercially available. An example might be a company offering Wenzel TGEAR XY software. This specialized software for the measurement of gears allows fully automatic measurement of the contour deviation (involute), line tooth pitch, and radial run out, tooth flank topography. If you do not have a special software to measure the gear, you require a measurement process based on 3D CAD model of the gear. It is necessary in this case, the preparation of a strategy based on measurements of 3D CAD model and load points or paths with the CAD model. The results of the measurement refer to the CAD model treating it as the nominal model. Item will present the methodology of measurement of cylindrical gears using a standard CMM software. Cylindrical gears can be measured through non-contacting or contacting methods – measuring point or scanning. The choice of measurement method should be carried out taking into account the accuracy of gear and taking into account the capabilities of the system and measurement needs. An important advantage of the measurement using the gears multipurpose measuring software is that it is possible to measure any geometry of the wheels in relation to the CAD model. Using this measurement strategy avoids the need to purchase additional software, the measuring machine and its setup. You should only choose a method of analysis that will be carried out directly in the environment-measuring machine, or will be made in the CAD system based on the geometry acquired during the measurement with respect to the virtual model. In the second case, export is needed in the appropriate format measurement data to CAD software.

Opis:: Manufacture of aircraft gearbox elements requires control of gear geometric parameters at different stages of technological process. In case of measurement of gear wheels using modern technologies based on numerical machines, measurement process is based on processing of numerical data obtained by measurement using coordinate measuring machines. The goal of this paper is to present the measurement process of gears, using coordinated optical scanner ATOS II TripleScan by GOM, equipped with a turntable. The aim of this study is to develop and execute the analysis accuracy of the geometry of the gear of aeronautical dual-power path gear after the roughing operation using optical coordinate measuring methods. Executed research will enable the detection of errors occurring in the machining process and to determine the value of founded the machining allowance finishing in relation to the CAD model. Using coordinate measuring technique, one can specify a set of methods and procedures for the designation of the complex dimensions of physical objects and transform them into a computer program space of coordinate measuring devices. On this basis, it is possible to determine the accuracy of the gear wheel as the workpiece prior to heat treatment. The results will be the basis to determine the effect of heat treatment on changes in the geometry of the gear and the benchmark for determining the correctness of the finishing.
